Problems solved by technology

Barnyard phosphorus can also be used for weeding in cotton, soybean, and rapeseed fields. The weeds that can be controlled include: barnyardgrass, crabgrass, foxtail, goosegrass, wild oats, special-shaped sedge, broken rice sedge, etc.; poor weed effect
At present, herbicides in paddy fields are limited by the safety of crops, and the herbicidal spectrum is also limited. Using a single herbicide alone cannot completely and effectively control the occurrence of weeds in paddy fields. Uniformity is also likely to cause residual toxicity to current crops or subsequent crops

Abstract

The invention belongs to the technical field of agricultural agents, and particularly relates to a mixed weeding composite containing bispyribac and aniloguard. The weeding composite takes the bispyribac and the aniloguard as main active ingredients, and the mass ratio of the bispyribac and the aniloguard is 1-99 / 1-99. Different surface active agents, thickening agents, solvents or solid fillers and the like are added to the weeding composite so as to be produced into missible oils, suspending agents, water dispersible granules, wettable powder and various dosage forms. The weeding composite can prevent and weed weeds of grass families, broad leaves and sedge families in paddy field, compared with a single herbicide, under the premise of improving the efficacy, the mixed weeding composite has the prolonged weed resistance, wide weeding scope and long duration, and is safe to paddy and succeeding crops.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to the field of herbicides, and relates to a mixed herbicidal composition containing bispyribac and saponin. The herbicidal composition has a remarkable effect of weeding after the rice field is applied. Background technique [0002] Bispyribac, also known as Nongmeili, bispyrimidine salicylate, chemical name: 2,6-bis(4,6-dimethoxypyrimidinyl-2-oxyl)sodium benzoate. It is a phenoxycarboxylic acid herbicide, which mainly inhibits the synthesis of acetic acid through roots and leaves and hinders the biosynthesis of branched chain amino acids. It is a selective herbicide and is used in direct-seeding rice fields with a wide weeding spectrum. Its structural formula is as follows: [0003] [0004] Salmonella phosphorus, also known as Aruojin. Chemical name: S-4 chloro-N-isopropylphenylcarbamoylmethyl O, O-2 dimethyl phosphorodithioate, the structural formula is: [0005] [0006] The...
